Depth

In jewelry, depth refers to the vertical measurement of a gemstone from the table to the culet.

Part of speech: noun
Definition: Depth is a critical dimension in the evaluation of a gemstone's quality and appearance in the context of jewelry making. It directly influences the stone's ability to reflect light, which is paramount in determining its brilliance and fire. A well-proportioned depth ensures that light entering the stone is optimally reflected within it and directed back through the top, enhancing the stone's sparkle. Conversely, a gemstone with incorrect depth proportions may appear dull or lifeless, as light may either escape from the sides or be inadequately reflected. Therefore, depth is a key factor in selecting gemstones for high-quality pieces, ensuring the stone's cut maximizes its visual appeal.
